How many foot-candles should be present in a janitor's closet?

A janitor's closet generally requires a minimum level of illumination to ensure that cleaning staff can safely and effectively perform their duties. The recommended level of illumination for utility areas, such as janitor's closets, is typically around 15 foot-candles.

This level allows staff to see clearly to handle cleaning supplies, equipment, and tools without causing accidents or making mistakes. Adequate lighting also helps in maintaining cleanliness and safety standards within health facilities.

Other options suggest levels that may not adequately support safe operations in such spaces. For example, a lower level like 5 foot-candles would likely be insufficient for detailed tasks that may require more visibility. Thus, the guideline of 15 foot-candles strikes a balance between energy efficiency and the practical needs of the workspace.
